"Application filed April 21, 1926. Serial no. 105,651.

This invention relates to improvements in boilers having particular reference to small steam. eneratinoboilers. r

i The objects attained in the invention consist in a quick action boiler having relatively high steam generating capacity, the boiler being without fines and simply designed in other respects for low cost production, the construction being such as will insure, dc,- pendable operation of the boiler with the minimum of maintenance. e

A feature of the boiler consists in a pinrality of removable tanks or-compart'ments,

one within another which serve for admitting and effecting gradual diiiusionrof cold Water in the boiler without materially checking thetemperature of the heated water, the arrangement being thus effective to maintain a uniform steam pressure.

The interposed relation of the tanks, one within another, and the further provision of a removable boiler head, also servesthe further double purpose of preventing or minimizing tha -formation of scale in the bottom of themain tank which receives the direct action of theheat, and affords coi1- venient accessibility to the interior of the,

boiler for removing from the inner tanks the accumulation of soft-sediments. V i

The improved. boiler is especially adaptable for small plants where a small supply of steam is required, astor sterilizing in dairies, and in preparing stock foods etc, for hand laundries and garment cleaning plants, for laboratories, etc.

In the accompanying drawings;

Fig. 1 is a view illustrating the boiler in elevation;

Fig-2 is a view. in vertical section.

As here sl1oWn the boiler consists of a suitable outer casing 1 which serves as the heat chamber, a conventional gas burner 2 as here shown serving tor-epresent any suit able heating means, a door 3' affording access to the heat chamber, a vent or smoke pipe 4L being connected to casing 1 in the usual manner. The main boiler tank is. suspended in casing .1 from a suitable con the bottom of tank 17, the outlet 19 being annular v The head 9 alfords suitable connections for the water supply line 11, steam riser line 12, a steam'pres-surc gauge 13, safety valve 14, the tank 5 being. further providedwith a water gauge 15.

Supported removably in tank 5 by means of-brackets 16 -16 is-a tank 17, the brack- V ets acting to effect an annular space 18 between tanks 5 and 17 thus to present ra shallow body of Water in cross section to the action ofthe heat in space 8 which results in quick heating of the water in s ace 18 and generating ofjsteam in the boiler. the rapid action being further accelerated by confining the water of lower temperature in tank 17, the water passing from tank 17 to tank 5 through an outlet 19 extended upward from the bottom of tank v17, thus the (ill water passing from one tank to the other,

water overflowing totank 17.- Tank 20 is supported free in the open end of tank 17 by means of overhanging brackets 21,thus when head 9 is removed tank 20 can also be removed and cleaned. Removal of the tank i also affords convenient access for cleaning the interior of tank 17. i i

The greater portion of the sediment from the water will remain intank 20 and the greater portion remaining suspended in the overflow water from tank 20 will settle in raised above the bottom to further minimize the passing of foreign matteror sediment to the outer tank 5. The sediment in tanks 17 and 20 will not readily form into scale because there is no direct action of heat on. the tanks, but will remain soft and can easily be cleaned out. The formation of sediment and scale in the outer tank will be so. slightthat it will be of little or noharm'ful consequence. I

From the drawings and the foregoing detailed description the improved construction and actionof the'boiler will be apparent and their importance in the efi'ective operation of small boilers recognized. i

Having described my invention,

I as;

l. A boiler comprising a heat chamber, an outer water tank supported in the heat chamber with heating space surrounding the tank, a second tank approximating in size the outer tank supported in and discharging into the outer tank with a shallow space between the tanks and a third open top tank supported in tllQSGCODCl tank acting to receive water supplied to the boiler and to discharge into the second tank.

20 supplied to the boiler.

3. A boiler comprising a heat chamber, a

water tank supported in and extended above said chamber, an open end, removable intermediate tank, approximating in size the outer tank, supported in and adapted to discharge into the outer tank through an outlet above the bottom of the intermediate tank thus permitting sediment to settle in the intermediate tank below the outlet, the relative size of the tanks serving to effeet a shallow space for water between the tanks, an inner removable tank supported in the intermediate tank for receiving water supplied to the boiler and overflowing into the intern'iediate tank, thus permitting sediment to settle in the inner tank, and a removable head for the outer tank for removing the inner tanks.

In testimony whereof, I affix my signature.
